So I have a view and in my viewcontoller class I try and add a subview with the following code .
UIButton *test = [[UIButton alloc]initWithFrame:CGRectMake(30, 100, 100, 100)];
[self.view addSubView:test];
Nothing happens, no errors or anything. I know its being called because it is in the viewdidload method. I have a separate class were i subclass uiview could that have anything to do with it?
UIButton *test = [UIButton buttonWithType:UIButtonTypeRoundedRect];
test.frame = CGRectMake(30, 100, 100, 100);
[self.view addSubView:test];
You need to make sure you add all the needed attributes of that button:
UIButton *test = [UIButton buttonWithType:UIButtonTypeRoundedRect];
[test addTarget:self action:#selector(selector:) forControlEvents:UIControlEventTouchDown];
[test setTitle:#"Button Title" forState:UIControlStateNormal];
test.frame = CGRectMake(30, 100, 100, 100);
[view addSubview:test];

I want to create the view with button, textbox, label programatically in viewdidload
But touch events are not working on view and its subviews even though i have set userinteractionenabled to YES.
Here is my code:
CGRect bounds = [[UIScreen mainScreen] bounds];
//creating a view
UIView* mainView = [[UIView alloc] initWithFrame: bounds];
[mainView setUserInteractionEnabled:YES];
[mainView setBackgroundColor: [UIColor yellowColor]];
CGRect buttonFrame = CGRectMake( 100, 80, 100, 50 );
UIButton *myButton = [UIButton buttonWithType:UIButtonTypeSystem];
myButton.frame = buttonFrame;
[myButton setBackgroundColor:[UIColor greenColor]];
myButton.userInteractionEnabled=YES;
[myButton addTarget: self
action: #selector(buttonClicked:)
forControlEvents: UIControlEventAllTouchEvents];
[myButton setTitle: #"My Button" forState: UIControlStateNormal];
//adding button to myview
[mainView addSubview: myButton];
//adding label to myview
UILabel* myLabel=[[UILabel alloc]initWithFrame:CGRectMake(100, 100, 200, 100)];
myLabel.text=#"my text";
[mainView addSubview:myLabel];
//adding textbox to myview
UITextField* textbox=[[UITextField alloc]initWithFrame:CGRectMake(100, 210, 200, 50)];
textbox.text=#"my text in textfield";
textbox.userInteractionEnabled=YES;
[mainView addSubview:textbox];
//finally adding my view to self.view
[self.view addSubview:mainView];
try this
//creating a view
UIView* mainView = [[UIView alloc] initWithFrame: bounds];
[mainView setUserInteractionEnabled:YES];
[mainView setBackgroundColor: [UIColor yellowColor]];
UITapGestureRecognizer *tapGesture = [[UITapGestureRecognizer alloc]initWithTarget:self action:#selector(tappedOnView:)]; //add the gesture to get the touch event
tapGesture.numberOfTapsRequired = 1;
[mainView addGestureRecognizer:tapGesture];
CGRect buttonFrame = CGRectMake( 100, 80, 100, 50 );
UIButton *myButton = [UIButton buttonWithType:UIButtonTypeSystem];
myButton.frame = buttonFrame;
[myButton setBackgroundColor:[UIColor greenColor]];
myButton.userInteractionEnabled=YES;
[myButton addTarget: self
action: #selector(buttonClicked:)
forControlEvents: UIControlEventTouchUpInside];
[myButton setTitle: #"My Button" forState: UIControlStateNormal];
//adding button to myview
[mainView addSubview: myButton];
//adding label to myview
UILabel* myLabel=[[UILabel alloc]initWithFrame:CGRectMake(100, 100, 200, 100)];
myLabel.text=#"my text";
[mainView addSubview:myLabel];
//adding textbox to myview
UITextField* textbox=[[UITextField alloc]initWithFrame:CGRectMake(100, 210, 200, 50)];
textbox.text=#"my text in textfield";
textbox.userInteractionEnabled=YES;
[mainView addSubview:textbox];
//finally adding my view to self.view
[self.view addSubview:mainView];
modify the line
//UIButton *myButton = [UIButton buttonWithType:UIButtonTypeSystem];
to
UIButton *myButton = [UIButton buttonWithType:UIButtonTypeCustom];
and add the method in your code
-(void)buttonClicked:(UIButton *)button
{
NSLog(#"hai");
}
and select the checkbox enable user interaction in interface builder its working fine.
I have a picture(UIImageView) and button(UIButton).
In this view I use QuickDialogController because it has many Element of Quick dialog in this view.
I want to add picture(UIImageView) and button(UIButton) in Section(QSection) of this View.
How to add it.
This is my example code.
// test Add Image
-(void) addImageView
{
image = [[UIImageView alloc] initWithFrame:CGRectMake(35, 60, 250, 250)];
[image setImage:[UIImage imageNamed:#"image.jpg"]];
[image setContentMode:UIViewContentModeScaleAspectFit];
[self.view addSubview:image];
}
// test Add Button
-(void) addRotateButton
{
button = [UIButton buttonWithType:UIButtonTypeRoundedRect];
button.frame = CGRectMake(125, 350, 70, 40);
button.backgroundColor = [UIColor lightGrayColor];
[button setTitle:#"Rotate" forState:UIControlStateNormal];
[button addTarget:self action:#selector(onRotateButtonClicked:) forControlEvents:UIControlEventTouchDown];
[self.view addSubview:button];
}
Thank you.
I think there are two ways to do this. The easiest way is to add the view with button and imageview to the section header.
# s is a Section, code is ruby motion
s.headerView = UIView.alloc.initWithFrame [[0,0],[300,1]]
image_view = UIImageView.alloc.initWithFrame CGRectMake(0, 0, 100, 100)
s.headerView.addSubview image_view
s.headerView.addSubview button
If you would like to add it somewhere else in the section. I think you need to make a new class that inherits form QElement. Haven't done this yet.
I've look at many responses and still cannot figure it out. I know the first line is a little weird, but its because it is inheriting from a super class that sets the headerview to search bar
searchBar = (UISearchBar *)self.tableView.tableHeaderView;
[[searchBar.subviews objectAtIndex:0] removeFromSuperview];
UILabel *label = [[UILabel alloc] initWithFrame:CGRectMake(0, -100, self.view.frame.size.width, 100)];
label.text = #"AAAA";
[searchBar addSubview:label];
UIButton *button = [UIButton buttonWithType:UIButtonTypeRoundedRect];
[button addTarget:self
action:#selector(aMethod)
forControlEvents:UIControlEventTouchDown];
[button setTitle:#"Show View" forState:UIControlStateNormal];
button.frame = CGRectMake(80.0, -60, 160.0, 40.0);
searchBar.exclusiveTouch = NO;
searchBar.userInteractionEnabled = NO;
label.userInteractionEnabled = NO;
button.userInteractionEnabled = YES;
[searchBar insertSubview:button atIndex:3];
userInteractionEnabled set to NO on a parent view will cascade down to all subviews. Thus, your instance of UIButton will appear unresponsive because the searchBar is disabled.
Here is your answer :
searchBar.userInteractionEnabled = NO;
If you are going to add a subview to a view that has userInteraction disabled then that subview won't receive touches. I haven't looked very good at your code to see if there are other mistakes.
Look at the frames in the first place :
button.frame = CGRectMake(80.0, -60, 160.0, 40.0);
UILabel *label = [[UILabel alloc] initWithFrame:CGRectMake(0, -100, self.view.frame.size.width, 100);
The button isn't visible at all , and the label the same , the objects are placed outside of bounds and that's why you cannot touch them.
Pls help.. i have this button in my subclass, when i addsubview it in my uiview, it cant be clicked, any idea?..thanks
the button in my subclass:
- (void)configureDate{
ChangeButton=[UIButton buttonWithType:UIButtonTypeRoundedRect];
ChangeButton.frame= CGRectMake(10, 20, 100, 30);
[ChangeButton setTitle:#"Change Date" forState:UIControlStateNormal];
[ChangeButton addTarget:self action:#selector(changeDate) forControlEvents:UIControlEventTouchUpInside];
[self addSubview:ChangeButton];
}
I added the subclass/button in my uiview:
dateClass = [[DateClass alloc] init];
[dateClass configureDate];
[myView addSubview:dateClass];
[dateClass releaseTable];
the button appears but is not clickable:(
Try this:
[myView addSubview:dateClass];
[myView bringSubviewToFront:dateClass];
Try setting BG color for both dateClass and the ChangeButton button to test.
- (void)configureDate{
ChangeButton=[UIButton buttonWithType:UIButtonTypeRoundedRect];
ChangeButton.frame= CGRectMake(10, 20, 100, 30);
[ChangeButton setTitle:#"Change Date" forState:UIControlStateNormal];
[ChangeButton addTarget:self action:#selector(changeDate) forControlEvents:UIControlEventTouchUpInside];
[self addSubview:ChangeButton];
self.backgroundColor=[UIColor redColor];
ChangeButton.backgroundColor=[UIColor yellowColor];
}
I've been using Interface Builder and storyboard to make my application, but for this signature capturing API, everything was done in code.
I'm trying to implement it to my application, but I can't figure out how to add an UIView and Buttons on to my scrollview.
I got it to appear in my view controller, but it isn't connected to the scrollview at all; it appears on top.
Here's my code.
- (void)viewDidLoad
{
[super viewDidLoad];
CGFloat padding = self.view.frame.size.width/15;
UIView *autoGraphView = [[[UIView alloc] initWithFrame:CGRectMake(padding, 300, 280, 160)] autorelease];
autoGraphView.layer.borderColor = [UIColor lightGrayColor].CGColor;
autoGraphView.layer.borderWidth = 3;
autoGraphView.layer.cornerRadius = 10;
[autoGraphView setBackgroundColor:[UIColor whiteColor]];
[self.view addSubview:autoGraphView];
self.autoGraph = [T1Autograph autographWithView:autoGraphView delegate:self];
[autoGraph setLicenseCode:#"4fabb271f7d93f07346bd02cec7a1ebe10ab7bec"];
[autoGraph setShowDate:YES];
[autoGraph setShowHash:YES];
UIButton *clearButton = [UIButton buttonWithType:UIButtonTypeRoundedRect];
// init withFrame:CGRectMake (50, 300, 200, 60)];
[clearButton setFrame:CGRectMake(padding, 480, 130, 30)];
[clearButton setTitle:#"Clear" forState:UIControlStateNormal];
[clearButton setTitleColor:[UIColor blackColor] forState:UIControlStateNormal];
[clearButton addTarget:self action:#selector(clearButtonAction:) forControlEvents:UIControlEventTouchUpInside];
[self.view addSubview:clearButton];
UIButton *autoDone = [UIButton buttonWithType:UIButtonTypeRoundedRect];
// initWithFrame:CGRectMake (50, 300, 200, 60)];
[autoDone setFrame:CGRectMake(150 + padding, 480, 130, 30)];
[autoDone setTitle:#"Done" forState:UIControlStateNormal];
[autoDone setTitleColor:[UIColor blackColor] forState:UIControlStateNormal];
[autoDone addTarget:self action:#selector(doneButtonAction:) forControlEvents:UIControlEventTouchUpInside];
[self.view addSubview:autoDone];
}
You need to add the subviews to the scrollview, if the root view of your viewcontroller is not the scrollview, you need to get access to it one way or another, typically through an IBOutlet, and add them that way
